| Research Abstract |
The purpose of this study is to evaluate price volatility risk and potential market power of generators in Japan Electric Power Exchange by using published data. We showed the volatility and the risk of price spike, which is one of the characteristics of electricity market, are smaller than those of European power exchanges in 2007. We could not conclude that there was an exercise of market power, since there is a general difficulty to analyze it for a power exchange where participation is voluntary.
